Add into that mix that require happens at run-time, use at compile and the notion that require pulls in the current namespace and voila - your subs are in your client namespace. (replace &sub_x with &Client::sub_x to see).

And that's why I try not to mix require with use. If I have global functions -- then either create a base class and let your Client class inherit them or create a util class and let your Client class use them.

By the way, you're probably not overriding that subroutine because the use statement is run before the require()s.

I'd be surprised if use strict; and use warnings; wouldn't catch the error, though.

Internal server 500 error.

I have just posted the code for Client.pm above...

That's not a perl error, that just whatever the webserver shows the browser. Look in the server's error logs, or better yet, try to run the script from the command line.

update: or try use CGI::Carp qw(fatalsToBrowser) at the top of your script.
